Abstract: Magnetic disk recording apparatus including a pair of magnetic transducers contacting the opposite sides of a magnetic disk and each carried by a swingable arm. The arms are interconnected together so that the swinging movement of one of the arms is transmitted to the other arm to cause an opposite swinging movement of the other arm for simultaneously moving the transducers away from the magnetic disk. An electromagnet actuates one of the arms so as to thereby also move the other arm.
